Transistors and semi-conductors no doubt. But since they are made from germanium or silicon, so logic gates can be made up of em'. Don't worry, they won't ask you to make one in paper 1 ;D ;D...

Has to be wavelength. Frequency and speed aren't measured in metres and I've never heard radios brodcasting waves with an amplitude of 200 metres :D.

E=mCT so T=E/mc = 4000/(2*400) = 5
A?

Ohhh I totally ignored the 40s. Thanks so much :D
